Chicken and rabbit in the same cage problem: there are a group of chickens and rabbits, the total number of legs is 2 times more than the total number of heads, 18, to find the number of rabbits Just tell me the formula and the solution
This is my own solution, I don't know if it is right
Suppose there are x rabbits and Y chickens
According to the meaning of the question, the equation is: 4x + 2Y = 2 (x + y) + 18
4x+2y=2x+2y+18
4x-2x=18
x=9
So there are nine rabbits
